Patent ES-296488-A1 (ES)
Title: Method of drying foamed materials, e. g. foods
IPC: A23L3/52
Filed: 1964-02-15
Abstract: A method of drying a foam, e.g. a food such as tomato paste or tea or fruit juice concentrates, consists in depositing the foam in a layer up to 0À1 inch thick on a moving support, applying heat by condensing a vapour on the underside of the support and passing a drying gas over the foam on the support. The layer is preferably 0À005-0À040 inch thick and the moving support is preferably an impervious, e.g. metallic, endless belt. The condensing vapour which applies the heat is preferably a mixture of air and steam, and the drying gas is preferably air at 140-210 F. moving at a velocity of 500-1500 ft./min. relative to the foam, preferably transversely to the direction of movement of the conveyer belt. At the terminal portion of the drying process the foam may be passed under an inert gas or a dessicated gas, and the end product may be treated with an azeotroping agent and re-dried. Food emulsion from hopper 10 and a foam stabilizing emulsion 12 are spread on to endless belt 26, preferably of stainless steel, by spreader 22. The foam layer passes under drying hoods 28 (see also Fig. 3) into which heated air is introduced at 29 centrally of the belt, moves transversely across the belt and is exhausted at 35. Instead of air, an inert gas may be used in the last drying hood. Under the belt, heat is applied by steam chests 30 into which a controllable proportion of air may be admitted at 33. As shown, the dried material is removed at 40, but alternatively the material may be left adhering to the belt and further drying effected by enclosing the lower run of the belt in a drying tunnel, the material being removed at the bottom of roller 23.

Patent ES-335922-A1 (ES)
Title: Spectral shift reactor control
IPC: G21C7/22
Filed: 1967-01-21
Abstract: In a liquid sodium cooled fast breeder reactor, spectral shift reactivity control is effected by variation of the concentration of lithium dissolved in the sodium. Sodium is extracted from the main coolant circuit and passed through a condensing tank and cooled to form separate high lithium concentration and high sodium concentration phases. A flow from the high sodium concentration is returned to the main stream. Rapid reduction of the reactor activity is effected by pumping the high lithium concentration phase directly into the reactor. Automatic reactivity control may be provided by either the adjustment of the condenser temperature or flow rate in accordance with the sodium temperature.

Title: Electrosharpening process
IPC: B23H9/08
Filed: 1968-01-16
Abstract: A process of electro-sharpening, e. g. of razor blades, tools, knives, needles or electrical contacts, comprises making the object to be sharpened the anode in an electrolytic bath and positioning in said bath an electro-positive control electrode relative to the area of the object being sharpened so as to influence and control the current density in said area. The control electrode is preferably as electro-positive as the object to be sharpened, or more electro-positive than said object, e.g. by using a circuit in which connections from the positive pole of the source of current to the anode to be sharpened and the control electrode are separated by a variable resistor (8), Fig. 1 (not shown). The control electrode may be positioned parallel to the apex of the blade edge, e.g. at a distance of 0À01 - 0À05 inch therefrom, or elsewhere with relation to the blade to produce a desired shape of cutting edge. A holder for supporting a razor blade during said treatment is shown in which the blade is connected to the source of current by conductor 34 and the counter electrode 16 is positioned parallel to the blade edge supported between members 36, one of which serves to connect said electrode to the electric supply. For sharpening of points, e.g. needles or electrical contacts, the control electrode may comprise a small bared portion of a wire covered by a thick insulating portion. The control electrode may be of stainless steel or of platinum, and for sharpening a razor blade a circular stainless steel disc may be used.
